      Set of utilities for testing the real-time behaviour of a

      Linux system.

​

      All tools are simple C programs with no dependencies, except

      the hwlatdetect utility, which is a Python script and

      therefore requires the Python interpreter. It will only be

      installed if a Python interpreter has been selected in the

      Buildroot configuration.

​

      Note that this package requires a toolchain built with the

      NPTL implementation of the pthread API (this is always the

      case with glibc/eglibc toolchains, but may not necessarily

      be the case with uClibc toolchains, since the thread

      implementation is configurable).
